'Information flow when redirecting from HTML to Servlet

I have a question regarding the information flow of a simple link. Let's say I have an HTML that does this:

<a href="servlet">Go to Servlet</a>

And in that servlet, I have a doGet, doPost, and a lot of other methods. Where does the information go to at first? Which block will be the first to kick in?

I know servlets shouldn't have all these methods and responsibilities, it's just a piece of code from a book (Professional java for web applications) that will introduce JSPs later on.
